The reverse purge valve is a 4-way valve designed to change the direction of the flow of the eluent through the nozzle column and blow off heavy components from the beginning of the column in the opposite direction into the detector. The crane is attached to the bottom panel (bottom) of the module, while taking the temperature of the column thermostat. The two upper fittings (see Fig.) are used to connect the column, the other two are connected to the evaporator and the detector.
